CRAYON POENTING AND LABELING MACHINE.

Application filed April 7, 1926. Serial No. 100,395.

This invention relates to a crayon pointing and labeling machine designed and adapted to automatically sharpen or point an end of arch crayon and apply to its body a paper label. The crayons operated on are soft, fragile, and of the type employed for marking lumber, black-boards, etc.

The main object of the invention is the production of machine for effecting the result referred to at low installation and maintenance cost, and capable of pointing and labeling a large number of crayons per minute. lVith this and other objects not specifically mentioned in view, the invention consists in certain combinations and constructions which will be hereinafter fully described and then specifically set "forth in the claims hereunto appended.

in the accompanying drawings, in which like characters 0% reference indicate the same or like parts, Fin. 1 is an end elevation of a machine constructed in accordance with the invention; Fig. 9. is aside elevation of the machine shown in Fig. i, as viewed in the direct on of the arrows in Fig. 1; Fig. 3 is a side elevation of the label magazine and label transferring device; Fig. 4t is an end elevation of the same; Fig. 5 is a vertical section through the crayon holding and forwarding turret; Fig. 6 is an end elevation of the turret; Fig. 7 is a horizontal section of the pointing device: Fig. 8 a vertical when of the same; and Fig. 9 is an end elea on of the point cutting device.

in carrying the invention into eliiect, there is provided crayon pointing means for forming a point on one end of each crayon, ejecting means tor discharging a pointed crayon from the pointing means. and means wherey cra are successively presented to said other means. in the best constructions contempla ed, there is further provided label applying means for applying a paper label to each crayon, either before or after said crayon pointed, but preferably before; and label and crayon assembling means whereby the labels and crayons are brought together preparatory to con'iplction of the label applying operation and ('Oll'll'l'lGIlCQ- ment of the crayon pointing operation. 'lhese various means may be widely varied in construction within the scope oi? the claims. for the specific structure selected to illustrate the invention is but one of many possible concrete embodiments oi the same. The invention, therefore, is not to be restricted to the precise details of the struc ture shown and described.

Generally speaking, the specific machine shown consists of a hopper in which a supply of unfinished crayons are supported and from which they are successively delivered by the action of gravity, a magazine in which a supply of paper labels are supported and from which they are successively delivered by the action of a suction transferring device, crayon and label assembling devices which carry labels and crayons from the magazine and hopper respectively to an assembling point, a paste applying device operating to make the labels adhesive in transit, a rotating crayon holding turret to which the assembled labels and crayons are delivered, devices for folding the labels about the crayons in said turret, a device for forming a point on each crayon in said turret after a label has been applied thereto, and an ejecting device serving to deliver the completely labeled and pointed crayons to a table or other receiving device.

The turret is provided with a series of crayon holding chucks which successively move into crayon receiving position. The label transferring device, by means of its suction head, successively takes the labels from the magazine, moves them past the paste applying device, and delivers them into assembling posi on over the crayon holding chuck which is in position to roceive a crayon and label. for further treatment. At the same time, the crayon trans ferring devices successively takes crayons from the hopper and delivers them into assen'iblying position over the label positioned over the turret chuclc. A plunger then moves label and crayon into said chuck where the are assembled with the mid-section oi the label stuck to the crayon while the ends of the label are in upstandin position above the perimeter of the turret. Then a folding device moves into engagement with the rear upstanding end of the label and folds it down on the crayon to which it sticks. The turret is then rotated a step, and during this movement the leading end of the label is folded down on the crayon by means of a stationary brush adjacent the path of the crayon holding chuck. Then the crayon pointing device comes into action and forms the point on one end of the crayon. The finished product is thenejected from the crayon holding means, ready for packaging.

Referring to Figs. 1 and 2, the machine is mounted on the frame 10 carrying an upright 11 on which is supported the crayon hopper 12 having the door 13. The lowestpart of the hopper terminates at the upper part of a chute 1% down which the crayons slide to the crayon transferring device.

The chute, to prevent accumulation of chips and dust, ismade in the form of a crate, the top and bottom consisting of two or more strips permanently fastened to the brackets 15 and 16. For accessibility, the front strip 17 is attached removably, being fastened to the-brackets 15 and 16 by means of the slotted crossbars 18 which permit its being lifted off after opening the door 13 which locks it when closed. In order to insure an uninterrupted feed of crayons through the chute 14., an agitator 19, pivoted on the pin 20, is mounted on the bottom of the hopper 12, the free arm 21 of the agitator being connected, through the rod 22, with the lever 23 which has an up and down motion.

The crayon transferring device, forming a part of the assembling means, consists of the slide 24, movable back and forth-in a guide 25 forming a part of the bracket 15, and being provided with a clamping bar 26 which holds the crayon against the end of the slide 2 f while being transferred. The bar 26 is attached to the forward ends of two horizontal rods 27 passing through the slide 24, their other ends being provided with springs-28 bearing against the slide 2%, and pushing the bar 26 toward the latter. The rods 27 are spaced a sufiicient dis tance apart to permit the crayons to pass lengthwise between them. The guide 25, on outboard brackets,carries the lugs 29 in which are supported the adjustable stop screws 30 registering with the free ends of the clamp bar rods 27. The slide 24: has the lug 31 which, through the link 32, is connected with the lever 33 from which the slide 2% receives its reciprocating-movement. The free ends of the rods 27, near the end ofthe back stroke of the slide as, when the crayon transfer approaches the delivery mouth of the chute 14, engage with, and are held stationary by, the stop screws 30, so that, on further backward movement of the slide 24:, the latter pulls away from the clamp bar'26, permitting a crayon to pass into the gap thus produced between them. The entering crayon proceeds into this gap until it is in line with the slide 24 and rods 27, when it comes to rest on the supports 34: projecting from the guide 25.

On the subsequent forward stroke of the slide '24, the springs '28 are gradually-re leased, and, when the ends of the rods 27 are out of engagement with the stop screws 30, draw the clamping bar 26 tight, thus iolding the crayon which by this time has moved clear of the supports 3%. lVhile the crayon transfer moves forward to bring the crayon into loading position or position for assembly with a label, the slide 24 closes up the chute let so that no crayons can pass out thereof unti the slide has returned.

The label magazine 35, shown in detail in Figs. 3 and 4t, is mounted on the slide 36 movable vertically in the upright 11, the slide 36 being connected, the link 37, with the lever 36 mounted on the shaft 39 which is supported in hearing brackets 40 and carries the arm ll actuated by the connecting rod 42. To the slide is fastenel the bracket l3 holding the adjustable end plates il of the magazine. azine is partly covered by the plate 15, allowing the'lowerinost label to hang down at one end.

The label transfer consists of the carrier &6 having the guide bars a? slidable on the track 18 supported on the upright 11. The carrier as, on the portion of its upper surface opposite the label magazine, has sue tion holes 49 communicating, through the suction ports 50 of the carrier a6 and the hose connect-ion 51 with the vacuum pump 52. Atthe center of the suction head, the carrier has a rectangular slot 53 so dimensioned that the crayon can pass through it on its way to the turret. The carrier the lug 5a to which is pivoted the adjustable connectingrod 55 connected with the lever 56. In feeding the label, the carrier 4-6 moved backward by the lever 56 until the suction head 49 registers with the magazine 35. Then, the slide 36 is moved downward until the free end of the lowermost label in the magazine touches the suction head which seizes and holds it fast, and, on the forward movement of the slide pulls it out of the magazine.

The label is carried past the paste apply ing device, the head of which, carrying the paste applying roller 5?, is raised, at the aroper time to allow the carrier to pass below it. Having previously been in con tact with the paste drum 58 revolving in the paste pot 59 adjustably mounted on the pedestal 60, the paste roller 57 applies a coating of paste to the upper surface of the label. The paste drum 58 is mounted on the shaft 61 which carries the gear wheel 62 meshing with the gear 63 which is mounted on the shaft 64 supported by the bearing bracket 65 and carrying the sprocket 66 which is driven by the chain 67 from the sprocket 68 mounted on the shaft 69. The paste roller 57 is supported on links T0 which are mounted in the head 71 with sufficient clearance to permit the paste roller The bottom of the mag- Ill? to rest on the label before the links are stopped by the head. The head 71 is sup ported by the connecting rod 72 which receives up and down motion through the roller 73 from the lever 7 1.

At the assembling or loading point, there is a plunger 1 ram 7 5 suspended by a link 76 from the end of the lever 23, and moving vertically in the guide 77. When the crayon transfer and label carrier have arrived at the loading point, the lever 23 pushes down the plunger 75, thereby forcing the crayon out from between the transfer slide 2 1 and the clamp bar 26 down upon the label on the carrier 16, and with the label through the slot 523 of the carrier into the receiving device or chuck of the turret. By its passage through the slot 53, the label is folded around the bottom and the two sides of the crayon, leaving the ends of the label upst-andin its the label carrier now moves back to receive the next label, the finger 78, attached at the forward end of the carrier by means of the lug 79. sweeps over the crayon now held in the turret chuck and thereby folds the rear upstanding end down upon the crayon to which is sticks. The other or leading end of the label is folded down on the crayon during subsequent forward rotation of the turret by the curved brush 80 mounted on the upright 11 adjacent the path of the turret chucks.

The turret, Figs. 5 and 6, whose body 81 is mounted on the shaf 82, holds the crayons in chucks one wall of which is formed by the turret body and til-8 other by a bar 83 which is pressed against a crayon by aspring 5341 supported in the bracket 85 attached to the turret body 81, the bar 83 being pivoted to the bracket 85. The crayon rests on the ll-shaped surface of a bar 86 which is fastened across the ends of push rods 87 which move the bar outwardly to eject the crayon at later time. The rods 87 have springs 88 held by collars 89 against the turret body 81. so as to hold the bars 86 down at the bottom of the chucks when the turret is moving and the rods are idle. The turret shaft 82 is journaled in the uprights 11 and 90 which, together, support the top member 91 of the machine frame. lhe turret is rotat d step by step by the action of the Geneva stop wheel 92 mounted on the turret shaft 82.

The point cutting device, shown in Figs. to 9, is supported in the housing 93 which at its ends has the bearing plates carryf the cutter shaft 95. The shaft has tool lead 96 holding the cutter 97, angu arly disposed with respect to the axis of the crayon acted on. The tool head 96 is provided with a dust shield 98 which throws the cut chips and dust into the chute 99 covered by the hood 100. pipes 101 leadmachine. it

ing them away from the end opposite the tool head, the shaft splined to the sleeve 102 on which is mounted the drive pulley 103. Within the l1G11S ing 93, on a ball bearing 10 1 attached to the shaft 95, is mounted the collar 105 which is engaged by the fork 106, to more toe shaft 95 back and forth toward and away from the crayon holding chucks in the turret. The fork 106 is mounted on the rod 10? slidably supported in the plates 91. On the rod 107 is fastened the adjusting block 108, adjusted by means of the screw 109, and connected by the rod 110 to the lever 111 which by its forward movement forces the rod 107 with the fork 106 towards the turret and thus carries the shaft 95 with the tool head 96 and cutter 97 into position to cut the point on the crayon. After the crayon is pointed, the cutting; head moves back, and, at the nextstation of the turret, the pointed crayon is ejected.

lhe ejecting; means is operated by the love 112 which moves towards the turret and presses again t the rods 8'? of the rhuci then. in discharg'i 9; position. The bar 80 carried by these rods is thereby moved outwardly and pusaes the crayon out of the chuck into the discharge chute 113 which fastened to the side of the frame 10 by means of the bracket 11 1.

The machine is driven by the motor 115 mounted on the frame 10 and carrying the pulley 116 which. through the belt 11'4", drives the pulley 118 con mine within it the clutch 119. The pulley 11S and clutch 119 are mounted on the shaft 120 supported by bearings in the frame 10. To the shaft 120 is keyed the pulley 1.11 driving, through the belt 122, the point cutting); drive pulley 103. The shaft 120 also carries the pinion 123 meshing); with the gear 124; mounted on the shaft 125 and driving; the gear 126 which is keyed to the shaft 127 having the pinion 128. The latter pinion drivs, throi ,i'h the gear 129, the cam shaft 130 on which are mount-- ed the cams 131, 132, 1841, 135, and 136. The cam 131. through the aller 13'2", open ates the lever 138 mounted on the shaft 139 in the bearing bracket 1 10. The lever 138, through the connecting; rod is connected to the lever 11 which moves tie label innate zine up and down. The cam 132, through the roller 1&1, actuates the lever 56 fulcrumed on the shaft 14-2 in the bearing; bracket 1 13, the said lever being connected. by the rod 55 to the label carrier 16 and in'iparlingr to the latter its reciprocating motion. The

earn 133, through the roller l il. operates the lever which, through the rod 1416, is connected to the arm 1 17 mounted on the shaft 118 which also carries the lever driving, through the link 82, the slide 21 of the crayon transfer. The lever 115 is mounted on the shaft 1 19 supported by the hearing brackets 150 and 151.
